A couple of tips I just thought I'd post.
For the animal in traffic, oil spills, animal attack: Use the KLEF (fire dept. van). The firefighters can "arrest" the dog, but only the KLEF can transport them away. You can do this for both animal attack and animal in traffic. If you shoot the dog, you need firefighters to remove the corps before the mission is completed.
For automatic firealarms, you need a ELW (command car) in addition to whichever other vehicles you need to put out the fire. Only the guy in the yellow vest can reset the alarm.
For traffic accidents, don't forget to clean up the oil.
The redirect command can be a bit tricky, but I've found that if you send the traffic to the next intersection, it works better for some reason. Might be coincidence though. On the "main street" in the middle of the map I redirect the traffic around the scene, not into the opposite lane.
In the missing child case, the kid is close to one of the trees. You don't need dogs (nor do you have them) to search for it. Just have a paramedic treat and transport.
For the homicide, you need the crime scene technicians to check the body. After they've done that, one of the people close to the scene will be revealed as the killer, IE draw a gun
Sometimes it can be difficult to spot him/her, other times he/she starts shooting at the crime scene people. I always call a patrol car to the scene when I send the crime scene techs. If the body is in the water, use the swift water rescue car found on the police page. It's the only one in the right most row.
EDIT:
To clean up the hose connector, you need to hold down Shift. That will give you the "Pick up" command
That's all I can think of atm.
EDIT-2:
Thanks for a great mod guys! The GUI is just amazing, the incidents are cool, models are sweet...oh, and the new SoSi logic is nice! Don't know how many have noticed, but at least the off map vehicles only switch the siren on when going through an intersection. Very realistic! One thing I'd like though, if it's possible, is for the sirens to turn on when they catch up to, and pass, a slower vehicle. I think the old one did that?
Will be get to use the BW-NAW, and Christoph 31 and Christoph Berlin in the future?
Especially the BW-NAW, I think that looks so cool
